Several security vulnerabilities were found in icedtea-web, animplementation of the Java Network Launching Protocol (JNLP).

CVE-2019-10181

It was found that in icedtea-web executable code could be injected in a JAR file without compromising the signature verification. An attacker could use this flaw to inject code in a trusted JAR. The code would be executed inside the sandbox.

CVE-2019-10182

It was found that icedtea-web did not properly sanitize paths from elements in JNLP files. An attacker could trick a victim into running a specially crafted application and use this flaw to upload arbitrary files to arbitrary locations in the context of the user.

CVE-2019-10185

It was found that icedtea-web was vulnerable to a zip-slip attack during auto-extraction of a JAR file. An attacker could use this flaw to write files to arbitrary locations. This could also be used to replace the main running application and, possibly, break out of the sandbox.

For Debian 8 "Jessie", these problems have been fixed in version1.5.3-1+deb8u1.

We recommend that you upgrade your icedtea-web packages.

Three security vulnerabilities have been discovered in the Dockercontainer runtime: Insecure loading of NSS libraries in "docker cp"could result in execution of code with root privileges, sensitive datacould be logged in debug mode and there was a command injectionvulnerability in the "docker build" command.

For the stable distribution (buster), these problems have been fixed inversion 18.09.1+dfsg1-7.1+deb10u1.
